This invention relates to rotary pumps for moving water, oil and various other liquids, and has as one-of its ob ects to pro vide a mechanically actuated pump 'in which valves of the usual type, and springs of any -fitted cylindrical valvesfiityprovided with Arfurther object isiin the prov1sionof an*rectili-nearports 35-ef uniform cross section "essentially compact, simple andefiicient'rog kind are wholly eliminated. 1

tary pump capablepflon'g and-continuous service. '7 ,5; 1 cw Another aim is to provide a pump that can be'chjeapl'y constructed, all partsbeing 1 of simple design.

These and like'other aims and objects are atta ned by the novel design," construction and combination of parts here1nafter fully describedand 'shown in] the accompanying. an essential part of'tlns drawing, forming disclosure, andv in which Figure 1 is a vertical sectional'yicwof a rotary pump made'in' accordance with the c center sockets 37 n "WlllClI are mounted invention.

Figure 2 is a s milar'view of the same, the parts be ng in a different position.

Figure 3 is a vertical sectional view, taken 7 .in a plane at a right angle to Figures 1 and 2, on line 3 3 of Fig. 1. Figure 4; is a top plan view of the same. Referring to the drawing in'greater detail, the pump casing comprises upper'and lower portions 13 and 12 having outer walls and 11, and inner walls 14 and 15 separated by a spacing plate 16. o,

The upper portion 13 has bolted to it a combined inlet and outlet manifold 17 in which are engaged supply *and discharge pipes 18 and 19 leading to chambers 20 and 21.

The chamber 20 has inlet openings 23 admitting the liquid to passages 24 and 25. be low which are cylindrical piston chambers 26 and 27. The passages 24 and 25 are sub stantially rectilinear, and extend from piston. chambers 26 and 27 to the inlet and outlet openings of the casing, their directions being substantially radial with respect to chambers 26 and 27.

A shaft 28 is journalled axially of-the piston chambers in the sides of the body,

mg adapted to make wiping contact with the walls ofthe piston chambers '26and as they arenloved ftherearound by the ec- 'centrics 29 and30.-'-"i- In the upper part of the casing are'other cylindrical bores 33] in which are rotatably.

manifold. As will bef's'e'enfrorn the drawing, each port 35 is adapted' t'o assume a position in substantialalin'ement with the passage 36 during the greater part of the pumping troke,tojthereby permit the passage of liquid tl'irough the outlet passage without substantial changc' of direction. The purpose of this arrangement 1s to minimize eddving and consequent frictional losses in the flow of the liquid 7 Both of thevalve's' 34'contain bored 01f round bars 38 to freely pivot therein. Ex-

plates 39. theirlowerjportions fitting transverse radial slots in the pistons 31and 32 respectively, these platesforming partitions between the inlet and outlet passages.

In operation, power beingtransmittedto the shaft 28, the eccentrics arerotatedcans,

ing the pistons to describe circuitous paths in contact with the'walls-of the'chambers 26 and 27 By reference to Figure 2 it'will be seen that water or like liquid entering through the pipe 18 will be divided to pass in two streams through the inlet openings 23 to thc passages 24: and obviously flow freely into the space between the walls of the pistons and piston chambers, this space constantly varying in volume.

The piston 31, moving in counter-clockwise direction forces the water around itself, and eventually through the port 35, and passage 36 into the chamber 21 and out of the pipe 19.

The other piston obviously operates in the same manner but in opposite phase, thereby producing a substantially regular and continuous flow through the pipe 19.

Having thus described my invention, what I claim as new and desire to secure by Let ters Patent, is

1. A rotary pump comprisingapair of similar body members havin 0 en upper chambers on one side of each 0 y and ontatable on said eccentrics, cylindrical valves 7 in, the mentioned .valveseats, said valves each having tangential ports vcommunicating with its corresponding chamber in said cover,- s aid valves having bores ad acent their,peripheryparall-el with;their axes and grooves leading thereto, pivots operative invthe bores of said valves, and plates on said pivots engagingradialslots n said cylinders, saidplates transmitting rotary motionto said valves and serving as closures between the sidesofthebody members and for the ports in said valves.

2. Ina rotary 'pump, the combination with a body having. registeringbored opens ings in its lower portion and similarly but smaller openings in git-S upper portion, a Y- cover removably secured on said ,body, a shaft rotatable axially ,1n the lower openings, eccentric fixed on said shaft in opposedrelation, rings revoluble on said eccentrics,-their peripheral surfacesmaking wiping contact with the inner surfaces of the walls of the lower openings,valvesrotatable .in the'upper open ngs, 831d valves having ports disposed in planes tangent tothe axis 1 of valve rotation, each of said valves having cylindrical openings disposed lengthwise at apo nt remote from-the center, pivots rotatable in the valve openings, and plates -fl i XCl in said pivots to extend radially into "-slots in the'periphery ofisaid rings, said plates acting as closures for the valve ports when intone position and as webs dividing the upper portionot said body.

3. A rotary pump for liquids, comprising a casing having a cylindrical piston chambers and substantially rectilinear iulct and outlet passages communicating therewith, an eccentric ring piston in said chamber, a cylindrical member rotatably mounted in said outlet passage, and a partition plate pivoted to said cylindrical member and fixed to said piston, said cylindrical member beto assumeia position in substantial alinement with said outlet passage during the greaterpart of the pumping stroke, to permit the-passage offliquid from said chamber through said outlet passage without substantial change of direction.

,4. {A rotary pump for liquids, comprising a casing having adjacent inlet and outlet openings, a cylindrical piston chamber, and substantially rectilinear inlet and outlet passages extending radially from said piston ring provided with a rectilinear port'adapted chamber tosaid openings, an eccentric ring piston in said chamber,a cylindricalmember rotatably mounted in said outlet passage, and a partition plate pivoted ,to saidcyliir drical member and-fixed to said piston, said cylindrical member being provided with a substantially rectilinear port of uniform cross-section adapted to a'ssume'a position, in

substantialalinement with said outlet passage during-the greater part of the pumping st roke,,to permit the passage of liquid through said outlet passage without substantial change of direction.

In witness whereof I have affixed my signature.
